Igneous Rocks
Igneous rocks are formed when this cools
Lava/magma
This is compacted and turned into Sedimentary Rock
Sediment
These are rocks that can become metamorphic rocks
Sedimentary rocks, igneous rocks
The three families that all rocks can fall into
Sedimentary, Metamorphic, Igneous
These substances make up all rocks
Minerals
This is rocks in liquid form
Lava/magma
When pieces of rock are broken off over time, by wind, rain, etc.
Erosion
These two things are required to form a metamorphic rock
Heat and pressure
A rock was originally just pieces of sediment. It then went under immense heat and pressure, causing it to melt. It then cooled inside of a volcano. What type of rock has this become?
Igneous rock
This is what we call minerals that are rare, with a brilliant luster or color
Gems
Liquid rock that is found inside volcanoes, and beneath Earth's crust
Magma
Compaction/cementation
Sandstone( a sedimentary rock) must go through this to become quartzite (a metamorphic rock)
Heat and pressure
These rocks can become sediment by erosion
All rocks!
Pieces of broken shells, rocks, and mineral grains are called this
Sediment
Igneous rock that is formed on Earth's surface
Extrusive Igneous Rocks
Sedimentary rock is the only type of rock that ________ can form in
Fossils
True or false: you could likely find a metamorphic rock sample while wading through a stream in the woods
False
Which type of rock would you not find on the ocean floor (this will require some thinking)
Metamorphic rock
a purple gem
Amethyst
This type of igneous rock is made when magma cools beneath the Earth's crust
Intrusive Igneous Rocks
True or False: you would likely find Sedimentary rock near the peaks of mountains
This type of metamorphic rock is usually bright in color, yet forms without distinct bands (strips) in it.
Non-foliated
A chunk of elemental carbon undergoes extreme heat and pressure. What family of rock does this become? what do we call carbon in this form?
Diamond
If a rock has a high silica content, it will be light in color. This is called what?
Granitic rock (granite)
